Oh yeah...552 = Commando 551 = SWAT or whatever. Either way the Commando markings made me feel like a Ninja Seal Viking.

I e-filed a Form 1. Unfortunately, the 552 from JDI wasn't on the drop down list. Now it's "pending research". I have another pending research that I've been waiting almost three months on.
I got the approved stamp, had it engraved and installed the stock today. I installed a US made three prong flash hider for the "Commando" look.

The other was a 5.45x39 Galil Ace pistol to SBR. Apparently, they didn't believe the 5.45x39 part. I submitted it on 10/27/20 and it was finally approved on 03/25/21.
The 552 is pictured above.
Unfortunately it's not marked Commando. There wasn't enough room after all of the importer's markings.
I shot it yesterday and it ran like a champ. I installed my 553LB's gas plug to see if it would make a difference. The ejection distance was significantly less due to its smaller gas port holes. Now I've got to figure out what optic to put on it.
